Cannot turn off Core_isolation_Memory_integrity

Question

Hello,

I have been dealing with this problem for 7 hours now, watching nearly 30 tutorials and reading 3 forums. I simply cannot deactivate core isolation. I have full admin rights, I've also disabled/enabled ( tried both ) VMX in the BIOS. Secure Boot is also disabled. However, I can't deactivate core isolation manually in Windows or in the BIOS. I've tried using the Control Panel, also with the Windows + R - regedit command, trying to manually change it to (Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity) and changing the value of (Enable) from 0 to 1 or vice versa. It just doesn't work. I've tried like 20 different methods.

I'm out of ideas and energy now.

Running on Windows 11 version 22H2.

I hope someone can help me here."

Also tried via windows Features activate / deactivate ( doesnt work too )

I want VMX and Core Isolation deactivated.

Answer 1

I have 3x Win11 devices here on 2 Core isolation is off & cannot be turned.

All devices are current models and are updated from the makers.

They all use the same Bus software & external HW.

MSFT are unable to rectify the problem
